Figure 5.

Experimental and simulated PRFs for screens 1–4. (first column) 40 kVp, experimental (second column) 40 kVp, simulations from MANTIS (third column) 70 kVp, experimental (fourth column) 70 kVp, simulations from MANTIS (fifth column) 40 kVp, horizontal cuts through the center of the PRFs, experimental data are shown with a solid line and MANTIS results are shown as a dashed line. The different screens are labeled as well as the incidence angles. Only incidence angles of 0° and 45° are shown. Contour lines shown on the plots are for levels of 0.01, 0.05, and 0.1 (the maximum is always 1). All PRFs are 101 × 101 pixels with 9 μm∕pixel.
